Re: Aluminum 5.3 lost oil pressure thoughts?

Your local dealer sells a lot of oil pumps because there's a bulletin on it to replace the oil pump for a sticking oil pressure relief valve. The bulletin is PIP4158H, doc ID 5392317 if you have access to GM Service Information. BUT, if the oil pressure light is on on the dash but a mechanical gaug...

Re: Anyone used the Blueprint Engines SBC Aluminum heads

Maybe hard to say in this day and age of copy cat parts. the off shore crowd sells head castings to anyone that wants to place a min. order. They will engrave them how ever you want as well for a small extra fee per set. Where I am going is without knowing which supplier they came from for sure its ...

Re: Aluminum 5.3 lost oil pressure thoughts?

X2 They have an aluminum body and steel pressure relief valve. After oil changes crap in the pan gets washed down from the upper engine area when fresh oil is added and the sucked up in the pump thus the relief jams causing low OP. There use to be a myth about what filter being used made this happen...

Re: New lifters on the way !!

They get changed weekly after every race would be one reason and they are mechanical so apples and oranges. So many issues with morel lifters bleeding down why chance the hyd. rollers till they get the QC fixed. I have many sets of the bushed lifters in marine BBC applications no issues since they ...

Re: SCAT 9000 Limits

Not sure what you call expensive. I am up here as well and the difference in cost for a std weight crank is not much more then a cast 9000 series when it comes down to it.
It depends on how you buy and from where you buy as to how many hands touch it before you get it.

Re: New lifters on the way !!

Mike Lewis is helping me with a set of Isky EZ-Roll Helix design bushed solid roller lifters. The current ones are 5 years old,they are an older Isky EZX bushed version,and I want to replace them before they de-laminate like the previous ones. I'm hoping that longevity of these ones is an increase ...

Much appreciated, ProPower engines! I plan to run Isky #707-STA valve spring retainers with the 295-D springs.

Thanks,

Harry
Confirm the step distance just to be safe.
Not what the book says but if you got the retainers in hand check that and get back to me.

Re: Isky 295-D Tool Room Springs Without Inner Damper

I use the 295D in place of the 6005 often just to make the job easier when there is a budget. The 295D works out the same rate in both cases with the retainer installed for testing. If you want to know what the spring rate is at max lift let me know what retainer you have or how deep the 1st step is...

Re: ? steel shim gasket for sbc 400 ?

The 10105117 will not fit. Its for 350 bore. Goes up as wide as 4.080. I have never seen a steel shim head gasket for the the 400 sbc. Sorry :( Just to be clear there is 2 gaskets listed by GM that get confused. I do not have the part numbers on hand but the std. vortec head gasket is the same comp...

Re: Isky 295-D Tool Room Springs Without Inner Damper

Why would you remove the dampener spring??? Is this to fit a un-modified GM vortec head??? Seems like a bad idea to remove it and chance breaking the spring but it has been done many times when the extra machine work is forgotten about till assembly of the budget don't allow for it at that point in ...

Re: ? steel shim gasket for sbc 400 ?

I get its more about cost then anything but a simple fix. The other option is Cometic.Custom order for the thickness you need. They can and do make thinner gaskets for a 4.155 bore application. I was told that either .015 or.017 was as thin as they can go in GM stuff. They are limited by the materia...
